I think the main reason I went with the 10.2 over the 9.2 was the superior clamp. Since I am primarily working on carbon fiber bikes, with carbon fiber seatposts (including one super narrow aero post) I wanted the best clamp mechanism with good stability and clamp pressure control so that I don't have to overtighten and risk cracking the seatposts. It only MSRPs fo $40 more than the 9.2, but if you look online I'm sure you can get it for cheaper than MSRP. Also the build quality seemed to be a little more robust. Not to say that the 9.2 is bad, but the 10.2 seems near bulletproof. When people see the 10.2 in the house, they immediately go "oh okay, you're serious about your bikes".
